Linux likes to use unused memory for caching, which is most likely what you're seeing. > 09:52:38 up 370 days, 1:39, 1 user, load average: 0.07, 0.02, 0.00 > 49 processes: 47 sleeping, 2 running, 0 zombie, 0 stopped > CPU states: 1.1% user 0.0% system 0.0% nice 0.0% iowait 98.8% > idle > Mem: 481492k av, 476232k used, 5260k free, 0k shrd, 88392k > buff > 350252k actv, 84k in_d, 10304k in_c > Swap: 979956k av, 59912k used, 920044k free 197564k > cached The buff and cached numbers are the important ones; apparently half your memory is being used to cache disk access.
